SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 582,585, dated May 111897.

A li ation filed March 26, 1896. Serial No. 584,910. (No model.)

To all whom it may concern:

Be it known that I, ALBERT L. GREENE, of the town of Oranston, in thecounty of Providence, in the State of Rhode Island, have invented acertain new and useful Improvement in Spectacles; and I declare thefollowin g to be a specification thereof, reference being had to theaccompanying drawings.

Figure 1 is a top plan view of my invention. Fig. 2 is a side elevationof a piece of wire swaged in a tapering form from which the temple ismade. Figs. 3 and 4 are respectively a top plan and a side elevation ofthe temple constructed according to my improvement. Fig. 5 is a planview of the upper or inner surface of the lower earpiece of the eyerim,and Fig. 6 is a section of the same as seen on line w w of Fig. 5. Fig.7 shows in plan view the parts illustrated in Fig. 5 with the temple inposition thereon, and Fig. 8 is a sectional view of the same, as seen online a; x of Fig. 7. Fig. 9 is an enlarged view of my invention in topplan. Fig. 10 is a view of my invention in central cross sectionlengthwise of the earpieces.

Like letters indicate like parts.

My invention relates to the temples of spectacles; and it consists inthe formation of the temple with an end circular in shape, centrallyperforated, and provided with a stud, in combination with the earpiecesof the eyerims, the lower of said earpieces being made with anarc-shaped channel or groove on its upper (or inner) side, in whichchannel or groove the stud of the temple moves when the temple ispivoted to said earpieces, as hereinafter particularly described.

In the drawings in Fig. 2 I show the form of the stock from which myimproved temple is made. It is a wire swaged into a tapering shape atand near one end thereof. The thick end of said wire is formed by asuitable die and plunger into a circular disk shape a, leaving thetemple 1) with the shoulders c 0, whose edges are at a right angle withthe disk portion a, but lie in an arc of the circular edge of said disk,as fully shown in Figs. 3 and 4. The disk portion a is centrallyperforated, as seen at d, and a short stud or pin e extends at a rightangle therefrom close to the opening d, as indicated in Figs. 3 and 4.

In Fig. 5 I show the lower curved portion of an eye-rim f, to which issoldered the usual lower earpiece g, having the usual circularlyshapedextension-piece h integral therewith. The earpiece g has ascrew-threaded hole 2'. The extension-piece his somewhat thinner thanthe earpiece g, as seen in Fig. 6, and has a central aperture or hole jwith a smooth bore. Said extension-piece h also has an arc-shapedchannel or groove ninety degrees in extent formed in the upper (orinner) side of said extension-piece h.

In Figs. 7 and 8 is shown the lower earpiece g with the circular disk atof the temple in position upon the extension-piece h, the holes (1 and jthereof, respectively, being in line with each other and the stud e ofthe disk a in the channel or groove is of the extensionpiece h.

In Fig. 9 I show the upper curved portion of an eye-rim f, to which issoldered the usual upper earpiece I, having a hole with asmooth bore.The upper earpiece Z has the circularly-shaped extension-piece m, with ascrewthreaded hole therein. The earpiece Zis somewhat thicker than theextension-piece m. The earpieces 9 Z are closed and clamped by the screw72., and the extension-pieces h m are closed and clamped by the screw 0.The disk portion a of the temple lies between the extension-pieces h m.The screw 0 serves as a pivot on which the temple turns.

When the temple is closed down to the eyerim, as in Fig. 7, the stud eis at one end of the curved slot or groove is, as indicated in saidfigure in dotted lines, and when the temple is extended to the wearingposition, as in Fig. 9, the stud e is at the opposite end of said slot.

It has been usual in spectacles as heretofore made to form a sharp prongor ridge from the hinge portion of the temple to act as a stop when thetemple is opened to the wearing position, which stop strikes against ashoulder on the exterior edge of the earpiece to limit the outwardmovement of the temple. Such sharp points or ridges are apt to catch inthe cloth or fabric of the pocket and so to fray and wear the same, andalso to scratch the skin when the spectacles are carelessly handled. Inmy improved construction this prong or ridge is entirely dispensed with.My stud-pin 6 serves as the stop and by its contact with the ends of thecurved slot or channel 70 limits the movement of the temple on its hingeorpivot. The stud-pin and channel are on interior surfaces and whollyconcealed from sight and can do no damage and do not aifeet theappearance of the article. The edges of the earpieces andextensionpieces are smooth, continuous, and symmetrieal.

I claim as a novel and useful invention and desire to secure by LettersPatent In spectacles, the combination of the temple I), made with theshoulders c, c, and having at its end the centrally-perforated disk a,the latter being provided with the stud e, which projects at a rightangle therefrom on one side and near the centralperforation, the eye-rimf, having the centrally-perforated ALBERT L. GREENE.
